Accidentally made a router device to become End Device (Aqara ZNCLDJ11LM) and want to know how to do it again.

[rbtw]

What happened?

After I upgrade driver frome ezsp to Ember (SLZB-06m firmware 8.0.2), start to receive network route error message and Device Aqara ZNCLDJ11LM (curtain driver) is only compliant to pre-21 revision. And adapter will get fetal error periodly and restart.

So I removed 4 x Aqara ZNCLDJ11LM from my zigbee network to try to make it more stable.

After a day, I try to repair these 4 device back to zigbee network, I have notice that 3 of these device labeld as End Device, which are green in map scan. The last one device is labeled as Router.

I have no idea how I did it. I try twice to make the last one to be End Device by re-pairing, But no luck
Any Suggestion what should I do?

How to reproduce it (minimal and precise)
No idea.... It just happened spontaneously.

1.41.0
